We have all the code behaving as we want it to, and the circuit responding to it we expected. The inputs and outputs are clearly observable, and moreover easily controlled. Unfortunately, the motor does not provide us with enough torque, and as a result does not turn the fan with a high enough velocity. Therefore, the whistle is not provided with enough directed air pressure to pass through it to make a noise. Despite this, the output of a motor turning could lead to a range of different functions to alert a passer-by that a flammable gas such as butane, or carbon monoxide is present.
Because of how we have designed and structured the breadboard and Arduino, we had to then distance the sensors, LEDs and motor, so they were easily visible. We did this by taking them off and connecting them with female to male cables. We then designed the box around this arrangement. It featured a lid with six holes, and a base to contain the circuitry.
In hindsight, we should of positioned the holes for each smoke sensor on opposing sides of the box. This would of made testing far easier and proving of concept far easier.
